It is preferred that each sash rail hc ol'thc in'gsz-l designates tysame uniform cross-section and prcl'crnbhv that shown in thc drawings.'lhc cross-scctioii ol the sash rail is best shown in Figs. t and 6. )isingle strip olY sheet metal is hcni y on itself alonglongitudinalilines lo torni thc molding 2l, which has a lint l'ncc .22substantially at i'lglit uliglts to l'ni't 222i.

`erably of such a depth thatI the respective sash rails, each rail beingably initered at its ends.

Figs. 4 and 6 show a reiter-able manner of connecting abutting rais.Some reinforcement, such as an angle iron 26, has one leg insertedwithin the hollow flange 25 of a rail end. lt is preferred that thewidth'. of each leg of 26 be sullicient to completely till the spacebetween the bottom face of pane seat 24 and the inner face of the outeredge of flange 25. In the upper part of Fig. 6 the abutting sash rail orstile 9 is abutted with its mitered end against the mitered end .of rail11 and with the otherleg of angle iron 26 thrust into its 'ilan'ge 25.The rail ends are then secured one to another, if desired, by suitablemeans, such as soldering, brazing, or In a siinilar manner each rail maybe secured to the inclosed leg of the angle iron. It is, however, to beunderstood that'the sash rails may be joined without the aid ol thereinforcing angle iron 26. Nevertheless, it is preferred to em loy theangle iron when joining the top railpof each sash to the abuttingstiles. Such a oint is shown in Figs. 4, 5, and 6. ln this case the legsof the angle irons 26 are tapped to receive screws 27 which extendthrough the side of the flange 25 to clamp the parts together. Byremoving the screws 27, the top rail may be readily detached and removedas an entirety. It may be replaced as readily. This feature permits aane to be slid home in the gropve seats 24 lile a shutter, where it maybe locked in place by the attaching of the top rail. lement 28 may beused in the seats 24. Any number of sash rails may be joined to theabutting rails so as to be removable as an entirety, the vsame as hasbeen described in connection with the top rails.

The sash bar or muntin, shown in detail in Figs. 3 and 7, comprises twobent metal strips and means to clamp them together. 29 is a molding striwith its two edges 30 and 31 bent inward y as shown. The edges 30 and 31engage the interior face of the anes as shown. A second metal strip 32ias each edge 33 and 34, doubled over on itsel'l and then outwardly.near the medial line of the strip as shown in Fig. The outturned edges33 and 34 form spacinv abutments. A strip or series oi' washers 3oengage the edges 30 and 31 and by means of bolts 36 or their equivalent,which pass between the edges of the panes 17 and 13 and suitably engagethe strip 32, the strip 32 is clamped towards the molding. The abutments 33 and 34 limit the clamping effect of bolts 36 vupon the twostrips which are prefspace between the strip 32 and the edges'BO and 31is the same as the Width of the other pane seats 34. At each end of themuntin the moldinrjr 29 is cut oil' on a curve, so as to iit themolding'of such as rail 1U.' The body porpreferesmas 'tion of strip 32is preferably sguared 0H,

leaving projecting tongues 33 ano 34a, being continuations of theabutments 33 and 34. These tongues are designed to iit snugly in apane'seat 24 of the sash rail and secure the muntin. If desired, theymay be long enough to penetrate the bottom of the pane seat 24 or maymerely engage the side walls of said seat and stop short-of the bottomci the pane seat.

With a sash built up as described from rail construction of the sectionshown, there is provided` a flange 25 on all edges of the sash andextending at right angles to a ilat face 22'. This lian e forms therunner and weather iange or the sash, particularly that on the Stiles.

Each jamb comprises a bent metal shell formed oi' a single strip ofmetal. The pulley face of each jarnb is formed with an integral partingridge 35 with vertical stile edges 36 and 37 at right angles to thefaces 38 and 39 of the jamb. The sash slide on opposite sides of `theseparting ridges, as

the vertical faces 36 and 37 and are retained in place by verticaluides, preferably angle strips 4() and 41, w ich are removably securedto the jarnb as shown. Mounted in the j amb there may be provided aclamping device or sash fast. Such a fast is indicated by 42. Its aws 43and 44 may be clamped against the anges 25 through the holes'45 and 46provided in the vertical face-s 36 and 37. Each jamb providessuitablefrunways for sash weights indicated by 47. A separating strip 48may be provided as shown 49 indicates suitable pulleys over which thecords or'chains, such as 50 may run. Removable sections may be providedin the jambs to give access to their interior. a section 1s indicated by51.

In the embodiment olthe invention illus trated the partinff'ffridges 35separate the sash a suthcient cistance to permit of the provision of asuitable interlocking weather closure for the meeting rails 1l and l13of the two sash. Secured to flange 25 of rail 13 is a bent metal.hook-shaped strip 52, coperating with a mating L-sha ed bent metalThese strips when interlocked cemplete'fan S-shaped weather closure asshown? The head 5 is similar to the jambs 2 and' 3,

but its parting ridge 54 is narrower than the of the lower sash, whensaid sash is raised. Angle strips 55 and 56 are preferablyaiiixed to thehead 'asshomnv to close againstV the flanges 25 of ytl'reftepy railswhen t re' sash is raised. The sill 4 comprises a bent metal shell openat the bottom and preferably iilled with concrete'indicatedi by 5TH-ltsupper face has an exterior inclined portion or shed 53.
